ABB ARC GUARD SYSTEM™

The phenomenon where a flashover of electric current leaves its expected path and travels through the air from one conductor to another, or to the ground is called an arc flash. Arc faults in medium voltage or low voltage switchgear is one of the most devastating fault types in electrical switchboards. The results are often intense and when a human is near the arc flash, serious injury and even death can occur. Most of the built-in protection systems aren’t enough to protect the switchboards in older installations. IPD offers ABB’s Arc Guard System™ which can detect light from the arc and signal the circuit breaker to disconnect the power, saving lives as well as equipment in switchgears, thereby significantly eliminating unnecessary production stops with long downtimes and destroyed equipment.

Our TVOC-2 arc guard system™ is SIL-2 certified according to IEC 61508 and IEC 62062 providing an unrivalled optical arc flash mitigation device with the fastest reaction time on the market. The TVOC-2 identifies the light from an occurring arc flash and transmits the signal to the breaker within 1ms. Along with ABB’s Emax 2 circuit breaker, the total arc fault clearing time is less than 50ms. The current sensing unit CSU-2 is an accessory to the TVOC-2 which will identify the current increase associated with an arc flash.

The ABB TVOC-2 Arc Guard System™ has a protection degree of IP54 with an HMI touchscreen that can be panel door mounted. It can be expanded with up to 30 optical sensors for a wide coverage from a single TVOC-2 and can be monitored remotely via Modbus RTU communication protocol. Its user-friendly start-up menu and calibration-free installation on either a DIN-rail or a wall mount makes it a quick solution with ensured reliable function.
